    in the cells of one person DNA is all the same, except for gametes. How is that all these cells perform so many different functions yet, all contain the same DNA in one organism?

    Because only the genes that are relevant to a specific cell type are expressed (turned on) in that cell. The key to multicellularity is in the proper ability to regulate and coordinate gene expression.
